The starting point

That’s the theory. But what is the real benefit of blue light filter glasses and how useful are they? That’s exactly what I want to find out in a two-week test. As a test person, I’m pretty good, because according to my own calculations, I spend at least every day of the week 10 to 12 hours in front of any screen: Since Corona, my entire working day has been spent in front of the laptop, which is often followed by zoom dates with friends or a cozy evening with a movie or series. In addition, there is private scrolling through online shops and Instagram. I hardly give my eyes any rest on weekdays – actually only when I’m sleeping. The consequences? From the afternoon they usually feel dry and irritated. They are always red in the evening. I also get frequent headaches. Actually no wonder…

My test glasses from Viu

The blue light blocking glasses I am allowed to test are from Viu Eyewear. The Swiss label for glasses and sunglasses has just brought a new premium blue light filter onto the market, which it says is unique because it shows no shimmer or residual reflections on the lenses. In other words: the blue filter glasses are not recognizable as such when they are worn. Since I need prescription glasses (I usually wear dimensionally stable contact lenses and want to give my eyes a break from that) and don’t know my current vision values, I make an appointment for a consultation including an eye test at the Viu flagship store in Munich. Here I get friendly and competent advice and store employee Daniela takes the time to determine my visual performance with an eye test. After the measurement, the test glasses are selected. I opt for a delicate titanium aviator-style model called “The Nomad”, which is minimalistic and retro at the same time.

Wearing the blue light filter test glasses

After two and a half weeks I can pick up my blue light filter glasses with additional prescription lenses from the Viu store. Here it is finally adjusted to my head so that everything fits perfectly. On the first day of wearing, I was still a bit “flashed” by the new visual experience of the glasses, the lenses of which have a higher diopter than my lenses. But I’m getting used to my better eyesight quite quickly. What I noticed right after the first day of my blue light filter glasses test: My eyes are no longer red and less dry in the evening. And that’s despite spending just as much time in front of the screens as usual. This condition lasts for the next 14 days, which actually makes me feel more rested and fitter. I only notice the blue filter of the glasses insofar as the white tones in my field of vision appear less glaring, which I find very pleasant.
